soreuseport: fix NULL ptr dereference SO_REUSEPORT after bind
Marc Dionne discovered a NULL pointer dereference when setting
SO_REUSEPORT on a socket after it is bound.
This patch removes the assumption that at least one socket in the
reuseport group is bound with the SO_REUSEPORT option before other
bind calls occur.
Fixes: e32ea7e74727 ("soreuseport: fast reuseport UDP socket selection")
